For most people, their day is a mix of different activities, and any discomfort or pain is not the result of a single, isolated activity. You might drive to the office in the morning, walk from the parking deck to your office, spend your morning at your desk, walk to lunch, spend your afternoon at your desk, drive home, go for a jog, then spend your evening on the couch before bed. If your feet hurt at the end of the day when you go to put your feet up, is it easy to identify which activities caused the discomfort? Not necessarily. It might be the walking, the shoes you wore to the office, driving during rush hour, running, your sneakers, or a combination of all of these.
Products that promote everyday comfort are products which can be used in almost any type of footwear, during any activity, and have features which are generally good all-around for promoting foot comfort and foot health.
